Pick up a new MAF, definitely. The car will run on 'preset' values but it won't be optimal at all.

 

I was reading around about much more affordable and supposedly even better MAF than the OE one... details here:

 

With the 'WEEKEND55' code on Euro Car Parts this weekend you can pick one up for just £55. Search on their site for the product code 434220200. You'll need a torx 'security' type tool (which is the torx bolt pattern but with a hole in the middle) as it appears to just be the MAF element that is supplied, not the entire housing.

I've read all 5 pages, seems likes dream solution!

I would stick with the original Bosch because the working profile on Pierburgs is different. CLICK

I see you commented on that thread chicaneuk and you seem to be the only one disagreeing....people had good results even after a few years. I can't see a negative in doing this swap....

To be fair, I was just regurgitating information I've read as a pretty new E39 owner. Clavurion, from what I've seen, really knows what he's talking about... so I'd only opt for the Pierburg MAF if I was on a budget given you can pick it up for like 1/3 of the price of the genuine Bosch one!

I've just ordered a brand new Bosch MAF, at least I know it will work properly - bought a full service kit too, oil, air filter, oil filter etc so going to get that fitted this weekend. 

 

Had to put my alloy refurbishment and paint issues to one side. 

 

Will update the thread when I have fitted the new Bosch MAF.

I would put this in the same category as the power boxes fouling rail pressure sensor giving a lower value compared to actual to get higher rail pressure and hence power.

Yeah I thought about it more and couldn't see any real benefits to fitting a part that wasn't supposed to be fitted.

 

Just hope the Bosch maf cures the problem.

I did plan to but went out Friday and had stuff to do Sat and today - definitely doing it next week, my maf should arrive tomorrow all being well.

 

I was going to do an engine flush but have read it's not advisable..

I flushed my engine with 6 litres of diesel when axle seal on HP pump failed. No problems. :lol:

Started doing the service, tried taking the oil filter cap off with the correct tool I just bought and this happened -

The hole is where I have had to drill into it and crack it in half to get it off - it was on ridiculously tight and the plastic hexagon nut sheared straight off.

 

So now I'm left with no car. Does anyone know where I can get a replacement oil filter cap asap as in tomorrow??

 

Going on holiday on Friday and don't want to leave it like this - I drained the oil so can't move it off the ramps!

 

Well annoyed.

Quarry motors in sheffield will have 1, or from any e46, e39 thats being broken near to you, there all the same petrol and diesel but later models have a solid hex nut on the top to stop that from happening, i had the same issue on my diesel.

Fecks sake. How tight must that have been done up to cause that!! The perils of home mechanicing sometimes :( Hope you manage to get it sorted in time for the weekend! 

 

You never know but worth ringing local BMW dealer I suppose? They might just have one on the shelf!

The older hollow hex caps dont need to be that tight for them to bust the hex bit off....esp with there age now....word of warning to all who have hollow hex nuts, replace with solid or at least have the replacememt ready when next oil filter is due.

I thought that, seems a stupid design to be honest, will ring the dealer tomorrow.

I have spoken to a guy who has one for a 2001 530i - he says it won't fit as it needs to be from a 525d or 530d m57 engine.

 

They all look the same to me?

I got mine from quarry motors in sheffield, a bmw specialist brakers and they told me they are all the same and they took one from a petrol e46 for my m57 530d and when i got it home i compaired them and they were identical apart from the replacement had the solid hex nut and the part numbers were the same. I would think the v8's would be the same but can only go from my expreiance

Thats odd, dont know why a bmw specialist brakers would say my replacement was from a petrol when they look nothing alike.

 

Unless he ment to say diesel e46 and blurted out petrol e46

Ah right, that's that then. Was only round the corner too.

 

I've messaged a few other breakers, wonder how much BMW will charge - the only one on ebay ships from Latvia so I doubt that will come tomorrow...

Online parts diagrams suppliers say $26.99? Part number is, I think, 11422247379 if you fancy ringing BMW for a quote.

Cheers, BMW came to the rescue! Ordered it in the morning and it was delivered by dinnertime. I picked it up after work - £31 all in so not too drastic, it came with all the gaskets too.

So this evening I changed the oil filter, oil and air filter. The oil was easy, there's a little flap built into the cover that protects the underneath of the car - this was really handy as I usually spend most of my time undoing loads of screws to get the covers off. 

Obviously the oil filter was a nightmare but only because it had previously been overtighted. 

The air filter was a bit of a mission! 6 screws to take the left engine cover off, you need to remove the cabin filter lid, then the pipe that connects the cabin filter to the interior, then lastly remove the whole cabin filter housing. It was easy enough just seems a bit long winded for an air filter.

 

I also sorted the leaking egr pipe where the mesh had blown out under pressure. This job took ages, mainly because the two torx bolts were blocked in by various pipes and the egr pipe itself. There was no way of getting a ratchet in there so I improvised with an 8mm spanner connected to the torx bit and slowly managed to get the bolts out.

One thing I don't understand is where that bracket goes now - it was connected to the egr pipe and now there is nowhere for it to go. Can't pull it off either.

 

So I have completed the service and blocked up the leaky egr pipe. I took it for a quick spin and it seems to drive smoother but a bit rough but that will be to do with having the maf unplugged. My new maf was despatched today so should be here tomorrow. Hoping it will be sorted when that's fitted.
